Summary of the invention
In the disclosed technology of TOHKEMY 2006-110225 communique, even carried out the pattern embossing, because the parts of embossed portion are white, although the light penetration difference of embossed portion visually also is white or color proximate with it with uniform state.Therefore wearer waits the bad place of light to be difficult to distinguish pattern in toilet when changing absorbent commodity.And, as the possible method that can clearly manifest embossing, handling under can only creating conditions in heat, pressure, gap etc., the result has the embossed portion hardening, causes the problem that pain, friction etc. are uncomfortable when touching skin.
Disclosed in TOHKEMY 2006-181192 communique, utilize knurling rolls to form in the recess in the method for the bottom of this recess transfer ink, might be when forming recess China ink ooze out and attached to accept on the roller, China ink also is transferred to beyond the recess etc., complex procedures, and is unrealistic.And, can not stably form recess or might the China ink that be configured in recess be moved to skin surface because of the body pressure of wearer.And, not with face that the skin of wearer directly contacts on printed patterns method or have following problem in the method for egative film printed patterns just can see pattern owing to will see through lateral plate, therefore the identity height of talkative pattern not.
Originally when dressing sanitary towel, had following problem for unfamiliar youngster or the women that haves no alternative but change at short notice etc., promptly, from want of experience or worry etc., forwards, backwards or ground, mistaken wearing position such as the oblique skew situation of installing in the majority, thereby cause leak or install uncomfortable.And also has following problem, promptly, the purpose of the embossing of implementing on absorbing surface is that situation about being provided with in order effect such as to prevent to leak is in the majority, but because formation method instability for example takes place to float when waiting, especially visually can not obtain the sufficient security or destroy the high-quality sense.
Absorbent commodity of the present invention have liquid permeability sheet, opaque liquid sheet and be clipped in this liquid permeability sheet and this opaque liquid sheet between absorber, it is characterized in that, on this liquid permeability sheet, recess is set, at least at the back side of the part that is provided with this recess and this liquid permeability sheet mutually ground connection have dyed layer, it is different with the color of part beyond the recess that this recess seems.
In optimal way of the present invention, recess is provided with by liquid permeability sheet, dyed layer and absorber being carried out simultaneously embossing processing.In addition, recess is provided with by liquid permeability sheet and dyed layer being carried out simultaneously embossing processing.In addition, absorbent commodity also has the second liquid permeability sheet between liquid permeability sheet and absorber, and recess is provided with by liquid permeability sheet, dyed layer and the second liquid permeability sheet being carried out simultaneously embossing processing.In addition, recess forms compression groove.In addition, the light penetration of liquid permeability sheet is below 70%.In addition, the thickness of liquid permeability sheet is at 3g/cm
2Under the load is 0.2～1.5mm.In addition, dyed layer is made of the thermoplastic resin that contains coloring agent.In addition, dyed layer is the coloring agent that relatively hot cladding resin 100 mass parts contain 0.1～10 mass parts.
Method of the present invention is the manufacture method of absorbent commodity, make following absorbent commodity, this absorbent commodity has liquid permeability sheet, opaque liquid sheet, be clipped between this liquid permeability sheet and this opaque liquid sheet absorber and at the dyed layer of the one side on the absorption side of this liquid permeability sheet, it is characterized in that, liquid permeability sheet and dyed layer is overlapping, process carrying out embossing in the zone that exists chromatograph from liquid permeability sheet side, on the liquid permeability sheet recess is set thus, it is different with the color of recess part in addition that recess seems.
Absorbent commodity of the present invention is owing to have a different recess of color, the pattern that therefore can clear identification ground recess forms, because dyed layer is configured under the liquid permeability sheet, so dyed layer does not directly contact skin surface simultaneously.
And, by color different liquid permeability sheet and dyed layer are carried out embossing processing, because the recess that is processed to form by embossing with the close mode crimping of the distance of liquid permeability sheet and dyed layer, is therefore seen the color of easy identification dyed layer at recess, from liquid permeability sheet side.

The specific embodiment
Below utilize accompanying drawing to describe, but the present invention is not subjected to the restriction of content shown in the accompanying drawing with regard to the present invention.
Fig. 1 is the vertical view of an embodiment of absorbent commodity of the present invention, and Fig. 2 is this X-X ' cutaway view.
Fig. 1 represents to have formed by recess the example of the sanitary towel of compression groove.Compression groove prevents the side leakage of menses, promotes menses to absorb.Compression groove surrounds the centre or is equivalent to groin (Gu Kuri り) part form curve.On such compression groove, wearer for example makes and should the most absorbent intermediary part that is surrounded dress facing to scavenge port ground, and near the curve of the sidepiece of core and the crotch portion curve of underwear are as one man dressed.At this moment, if because of having carried out the compression groove that painted boldness increases, even the babe in the wood or under the situation of worrying in toilet etc. the dark place of light also can judge absorbing surface moment, correctly be worn on the target location, can prevent the leakage or the sense of discomfort that cause because of the skew of dressing the position.Because compression unit manifests color, the shape that surrounds is more eye-catching, and the visuality that always depends on the compression groove of embossing intensity is strengthened.As a result, have from visually alleviating effect the uneasiness of leaking.
By simultaneously liquid permeability sheet, dyed layer and absorber being carried out embossing processing recess is set, can forms so coloured compression groove.
Fig. 3 is the example that has formed the sanitary towel of pattern by recess on liquid permeability is unilateral.Fig. 4 and Fig. 5 are the cutaway views of its Y-Y '.As shown in Figure 3, can recess 6 be set at the pars intermedia of the absorbing surface of liquid permeability sheet 2.Such recess, can be as shown in Figure 4, liquid permeability sheet 2 and dyed layer 5 be provided with by being carried out embossing processing simultaneously, or as shown in Figure 5, under the situation that has the second liquid permeability sheet 7 to exist, be provided with by liquid permeability sheet 2, dyed layer 5 and the second liquid permeability sheet 7 being carried out simultaneously embossing processing.Implement under the situation of embossing at the central part to the absorbing surface of liquid permeability sheet, especially this embossed portion is the zone that possible contact with labia or clitoris, therefore, processes hardened part because of embossing and contacts, has easily foreign body sensation with this sensitive part.In the present invention,, do not carry out embossing processing, obtain the identity of recess easily yet even exceedingly do not apply heat or pressure owing to have dyed layer.And, owing to be provided with dyed layer in the menses absorption region, therefore not even to underwear but also moment identification absorption region of the empirical people of sanitary towel is installed, thus the tram can be installed in, and also can reduce discomfort when using by the effect that pattern hides menses.Except patterns such as flower shown in Figure 3, also can consider different shapes such as quilting shape or point-like.
The pattern 9 of compression groove 8 and absorbing surface central part also can be set as shown in Figure 6, simultaneously.This example is overlapping successively liquid permeability sheet, second liquid permeability sheet and the absorber, has dyed layer between the liquid permeability sheet and the second liquid permeability sheet.In this example, at first liquid permeability sheet, dyed layer and the second liquid permeability sheet are carried out embossing processing simultaneously, be formed with the recess of colored pattern at the central part of the face of use, then, to the liquid permeability sheet, color chips, the second liquid permeability sheet and absorber and carry out embossing processing simultaneously, form coloured compression groove, make thus.
Fig. 7 is the example that recess is set at the position that does not have absorber.Fig. 8 is its Z-Z ' cutaway view.Can such recess 6 be set by liquid permeability sheet 2, dyed layer 5 and opaque liquid sheet 3 being carried out simultaneously embossing processing.Under the situation that has the second liquid permeability sheet between dyed layer and the opaque liquid sheet, can be provided with by liquid permeability sheet, dyed layer and the second liquid permeability sheet or liquid permeability sheet, dyed layer, the second liquid permeability sheet and opaque liquid sheet are carried out embossing processing simultaneously.
Absorbent commodity of the present invention is preferably as uses such as sanitary towel, diapers.When using, dress in the mode of the contact skin of the face of liquid permeability sheet and wearer as sanitary towel or diaper.
For the shape of absorbent commodity, if sanitary towel,, then be not particularly limited so long as rectangle, ellipse, Pear-Shaped, be equipped with and prevent with the so-called fin of underwear dislocation etc., meet the shape of female body and underwear shape.The overall size preferred length direction of profile is 100～500mm, more preferably 150～350mm.In addition, width is preferably 30～200mm, more preferably 40～180mm.
The liquid permeability sheet that constitutes absorbent commodity of the present invention has the function that the liquid discharges of ex vivos such as making menses, urine sees through to the absorber that is arranged at its lower floor, and by absorber is clipped in and the opaque liquid sheet between keep absorber.Whole or a part of liquid permeability sheet is a liquid permeability, and saturating territory, liquid zone is formed by the non-woven fabrics of the resin film that has formed many liquid drain hole, the net slice with many meshes or liquid permeability or woven etc.Above-mentioned resin film or net slice can use the material that is formed by polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET) etc.Non-woven fabrics can use the aspunlacednonwovenfa,ric that forms as cellulose fibres such as staple fibres, by synthetic resin etc. in addition, the hot-wind nonwoven cloth that formed by synthetic resin fiber etc.Raw material also can use biodegradable natural things such as polylactic acid, chitosan, poly-alginic acid in addition.In addition, also can when forming many liquid drain hole, apply the water proofing property interfacial agent of silicon class or fluorine class, body fluid is difficult to attached to its outside.
The weight per unit area of liquid permeability sheet is preferably 15～100g/m
2, 20～50g/m more preferably
2, 25～40g/m more preferably
2If the not enough 15g/m of weight per unit area
2, then can not obtain enough surface strengths, might be damaged in use.And if be higher than 100g/m
2, then feel really up to the mark, sense of discomfort is in use arranged.And under long-time situation about using, in case be higher than 40g/m
2, then become with liquid permeability sheet maintenance liquid, keep slimy state always, will feel under the weather.Density is 0.12g/cm in addition
3Below, so long as liquid permeability, then be not particularly limited.If density is higher than this value, then be difficult to unobstructedly by between the fiber of liquid permeability sheet.Since the viscosity height of the viscosity ratio urine of menses etc., therefore preferred low-density.
If constituting the territory, saturating liquid zone of whole or a part of liquid permeability sheet is the perforated films such as thin film that formed many liquid permeable apertured, then the preferred aperture footpath is in more than or equal to the scope of 0.05mm smaller or equal to 3mm, spacing in more than or equal to the scope of 0.2mm smaller or equal to 10mm, open area ratio more than or equal to 3% smaller or equal to 30% scope in.
If the light penetration of liquid permeability sheet is too high, exist in the part of not implementing embossing under the situation of chromatograph, see through the color that liquid permeability sheet side can be seen dyed layer, though that recess seems color is darker, may become so unobvious.Therefore, the light penetration of liquid permeability sheet is preferably below 70%, and further preferred 30%～65%.The liquid permeability sheet need not be a white, as long as recess can be identified as different colors, also can be the color beyond the white.For example can be by obtain the liquid permeability sheet of ideal light penetration to liquid permeability sheet mixed colorant.For example will make the liquid permeability sheet still for reduce light penetration whitely, use titanium oxide, making the whole relatively fiber of its combined amount is 0.1～50 quality %, is preferably 1～10 quality %.As the method for the light penetration that reduces the liquid permeability sheet, for example dwindle the method for the fibre diameter that constitutes non-woven fabrics in addition in addition.In this case, suitable fiber thickness scope is below the 6.6dtex, to be preferably 0.1～3.3dtex.
The thickness of liquid permeability sheet (volume) is under the situation of non-woven fabrics at the liquid permeability sheet, even the weight per unit area identical materials, in case, also see through non-embossed portion easily and see color because of embossing etc. makes volume disappear.In addition, in case be compressed the thermoplastic resin that then might infiltrate, therefore material require thickness, the volume to a certain degree that uses as the liquid permeability sheet.The thickness of liquid permeability sheet is preferably at 3g/cm
2Load down for more than the 0.2mm, 0.3～1.5mm more preferably.
The liquid permeability sheet also can use the nonwoven cloth material or the perforated film of perforate.In this case, from the color that original aperture portion is directly seen dyed layer, can see through non-aperture portion and see color.In addition, in case further implement embossing processing, then obtain embossed portion and manifest three kinds of dark states, the bore portion of perforate seems also picture pattern.Therefore the trend that the sheet of perforate has volume to increase because of the formation of rib portion can effectively keep the distance with dyed layer as mentioned above.And, under using, do not have thickness though the light penetration of itself is low with the situation as the opaque liquid thin film of main body such as polyethylene, polypropylene.But, by make thin film roll the back with dyed layer bonding or by implementing Gear Processing etc. with the dyed layer partition distance, can relax seeing through of dyed layer color on the non-recess.
Absorbent commodity of the present invention also can further be provided with the second liquid permeability sheet between liquid permeability sheet and absorber.The raw material of the second liquid permeability sheet (for example non-woven fabrics) is similar with above-mentioned liquid permeability sheet, uses than the high slightly material of above-mentioned liquid permeability sheet density, and it is in order to improve liquid discharge property or to make liquid be difficult to reflux that the second liquid permeability sheet is set.
Absorbent commodity of the present invention also can further be provided with bed course between liquid permeability sheet 2 and the absorber 4 or between the second liquid permeability sheet 7 and the absorber 4.
The opaque liquid sheet that constitutes absorbent commodity of the present invention has the function that liquid such as the menses that prevent to be absorbed bulk absorption, urine spill to the outside, and use can prevent the material that such liquid spills to the outside.And by the raw material that uses liquid-tight but have breathability, sultry when capable of reducing using reduces the sense of discomfort when using.As such material opaque liquid thin film based on polyethylene (PE), polypropylene (PP) etc., breathable films are for example arranged, the composite sheet etc. of lamination opaque liquid thin film on the one side of non-woven fabrics such as spunbond shape.Can preferably use the laminate of hydrophobicity non-woven fabrics, impermeability plastic sheeting, non-woven fabrics and impermeability plastic sheeting etc.And, also can be the SMS non-woven fabrics that clips the melt spraying non-woven fabrics of enhanced water resistance with high-intensity spunbond shape non-woven fabrics.
Constitute the absorber of absorbent commodity of the present invention owing to have the function that absorbs and keep liquid such as menses, urine, thus preferred volume greatly, not yielding, material that chemical stimulation is few.The absorber that for example can use Time of Fluff Slurry or air-laid nonwoven fabrics and superabsorbent polymer to form.For example also can use artificial fiber cellulose fibers such as chemical pulp, cellulose fibre, artificial silk, acetate fiber to replace Time of Fluff Slurry.The weight per unit area that for example is paper pulp is 500g/m
2, the weight per unit area of polymer is 20g/m
2(distribution of polymer is in integral body) is 15g/m with weight per unit area
2Thin paper encase the material of paper pulp and the equally distributed mixture of polyalcohol integral.Air-laid nonwoven fabrics for example is to make paper pulp and synthetic fibers carry out thermal welding or carry out adherent non-woven fabrics with binding agent.Superabsorbent polymer (SAP) has water soluble polymer and has carried out suitable crosslinked tridimensional network, though absorb hundred times～thousands' times water, but be water-fast in essence, even also can be not dried up, for example be the graininess or the fibrous polymer of starch based, acrylic compounds, amino acids in case absorbed water is brought some pressure to bear.The shape of absorber and structure can change as required, but the absorbtivity of absorber integral body must meet design insertion amount and desirable purposes as absorbent commodity.The size of absorber, absorbability etc. also change according to purposes in addition.
The dyed layer that constitutes absorbent commodity of the present invention must be configured in the part that is provided with recess at least, and the scope of configuration dyed layer can be that whole liquid permeability sheet also can be a part of liquid permeability sheet, also can be layered configuration.
Dyed layer must be different with the color of liquid permeability sheet.Though also consider to influence to wait at heart to select this color, any color can.The material that constitutes dyed layer for example is China ink, coating, contain the resin (pigmentary resin) of coloring agent, sneaked into the non-woven fabrics of coloring agent or in surface applied the non-woven fabrics of coloring agent (painted non-woven fabrics), sneaked into the thin film of coloring agent or in surface applied the thin film of coloring agent (coloured film) etc., so long as colored materials gets final product, be not particularly limited, preferably contain the thermoplastic resin of coloring agent.The thermoplastic resin formation thin film or the flaky material that will contain coloring agent in addition also can be used as the dyed layer use.Use at dyed layer under the situation of the thermoplastic resin that contains coloring agent, add man-hour having implemented heat embossing from liquid permeability sheet side, the heat fusion that the thermoplastic resin that constitutes dyed layer applies during because of crimping is infiltrated and is fixed on the liquid permeability sheet, so the color of embossed portion seems darker than its peripheral position.Use at dyed layer under the situation of painted non-woven fabrics or coloured film, different when containing the thermoplastic resin of coloring agent with use, be not that thermoplastic resin melted by heating, infiltration are fixed on the liquid permeability sheet, but engage and have certain thickness liquid permeability sheet and dyed layer by implementing embossing, because it is closely fixing in its distance of recess, therefore compare with non-recess, see the tone of dyed layer from the liquid permeability sheet side of recess easily clearly.Also can betwixt apply thermoplastic resin in order to keep the crimped status of liquid permeability sheet and dyed layer this moment.The for example following non-woven fabrics that obtains after painted promptly, is sneaked into the coloring agent that pigment etc. constitutes in advance in the resin that constitutes synthetic fibers, carry out fibre spinning and obtained passing through painted fiber from this resin, and this fiber is formed non-woven fabrics.Equally, also by in the resin that constitutes thin film, sneaking into the coloring agent that pigment etc. constitutes in advance, utilize this resin carry out sheetization through painted thin film.
Coloring agent can use dyestuff or pigment.Dyestuff for example be with C.I sun blue etc. be representative direct dyes, with C.I reactive blue etc. be the reactive dye of representative, blue No. 1 etc. to be the acid stain etc. of representative.Pigment can use inorganic pigment or organic pigment, and organic pigment for example is red No. 404 etc.
If dyed layer is the thermoplastic resin that contains coloring agent, then amount relatively hot cladding resin 100 mass parts of coloring agent are preferably more than 0.1 mass parts, more preferably 0.1～10 mass parts.If the amount of coloring agent is very few, then recess is of light color, and pattern is not obvious, if the amount of opposite coloring agent is too much, the color of the part beyond the recess also deepens, and pattern is not obvious.
If the light penetration height of permeability sheet, the then color that also can see dyed layer beyond the recess.And if the coloring agent composite rate of dyed layer is low, then the recess tone peripheral with it does not have big difference, do not reach initial purpose.Here the difference of the tone of recess and non-recess (aberration) importantly.Feel that the non-recess of tone difference and the aberration scope of recess are more than the Δ E=6, preferred Δ E=6～Δ E=10.In addition,, can use colorimeter (manufacturing of Minolta company), permeability sheet and dyed layer are lumped together measurement aberration benchmark, remove the permeability sheet afterwards, only measure dyed layer, measure value of chromatism Δ E thus for aberration.Here the Δ E that just represents aberration describes, and the L*a*b* colour system is at present in the widely used colour system of every field, carries out standardization by International Commission on Illumination (CIE) in 1976, is used to represent the color of object.In the L*a*b* colour system, L* represents brightness, represents to illustrate the colourity of form and aspect and saturation with a*, b*.With a* be red direction ,-a* be green direction, b* be yellow direction ,-b* is the direction that the mode of blue direction is represented color, the big more color of numerical value is distinct more.In the occasion of L*a*b* colour system, with the numeric representation aberration of Δ E*ab, the aberration of two kinds of colors of an available numeric representation.Calculating formula is Δ E*ab={ (Δ L*) 2+ (Δ a*) 2+ (Δ b*) 2}

If pay attention to the visuality of aberration for dyed layer, then the liquid permeability sheet can be a white, but to there is no need be white.The color of chromatograph vis-a-vis for example, the liquid permeability sheet uses the opposite color in the form and aspect also can improve above-mentioned contrast.By using different colors like this, mixed in addition in these two kinds of colors of recess, show the third color.For example, if the liquid permeability sheet is red, dyed layer is blue, and then recess shows purple.
Absorbent commodity of the present invention can followingly be made, that is, overlapping liquid permeability sheet and dyed layer carry out embossing processing in the existence zone of liquid permeability sheet side to dyed layer, on the liquid permeability sheet recess is set thus.At this moment, overlapping successively opaque liquid sheet, absorber, dyed layer and liquid permeability sheet are processed implementing embossing in the existence zone of dyed layer from liquid permeability sheet side; Perhaps overlapping successively absorber, dyed layer and liquid permeability sheet, to implementing embossing processing in the existence zone of dyed layer, absorber and the liquid permeability sheet that will implement embossing processing then overlap on the opaque liquid sheet from liquid permeability sheet side; Perhaps overlapping liquid permeability sheet and dyed layer, from liquid permeability sheet side to implementing embossing processing in the existence zone of dyed layer, then according to opaque liquid sheet, absorber and implemented embossing processing the liquid permeability sheet order and that dyed layer is carried out between absorber and liquid permeability sheet is overlapping.That is, the opaque liquid sheet with and/or absorber can be overlapping at embossing first being processed and dyed layer and liquid permeability sheet, also can be overlapping with dyed layer and liquid permeability sheet after embossing processing.
Dyed layer can be arranged on the part of preparing to be provided with recess at least of liquid permeability sheet in advance.In this case, with the liquid permeability sheet that is provided with dyed layer in advance separately or make the liquid permeability sheet be provided with the overlapping with absorber of dyed layer one side towards absorber one side ground, implement embossing in the zone that liquid permeability sheet side direction dyed layer exists to process.
And dyed layer can be arranged on the part of preparing to be provided with recess at least of absorber in advance.In this case, the liquid permeability sheet is overlapped on the face that is provided with dyed layer of absorber, in the zone that liquid permeability sheet side direction dyed layer exists, implement embossing processing.
And, the double-layer tablet of prepared lamination in advance liquid permeability sheet and dyed layer, this double-layer tablet is maybe overlapping with the mode and the absorber towards absorber one side of dyed layer side with this double-layer tablet separately, implement embossing processing from liquid permeability sheet side.
And, also can form recess the liquid permeability sheet having been implemented embossing processing after, dyed layer is configured in the back side of liquid permeability sheet, in its lower section with absorber and the configuration of opaque liquid sheet.In this case, the part that is arranged on the recess on the liquid permeability sheet is thinner than the part beyond the recess, more can see configuration dyed layer in its lower section clearly, so the color of recess seems different with recess part in addition.
Dyed layer preferably uses the thermoplastic resin that contains coloring agent, the preparation at least that in advance dyed layer is coated in the liquid permeability sheet is provided with on the part of recess, with having applied the liquid permeability sheet of dyed layer, in the zone that liquid permeability sheet side direction dyed layer exists, implement embossing processing so that the mode towards liquid permeability sheet one side that is provided with dyed layer one side of liquid permeability sheet overlaps on the absorber.
If use the thermoplastic resin that contains coloring agent, can show new pattern by making up this modes of application and pattern embossing.To contain the method that the thermoplastic resin of coloring agent is coated on the liquid permeability sheet has: utilize slit type coater full coat pattern (not having blank portion), utilize the blank portion of having of slit type coater pattern (striated), utilize the coating (waveform) of control joint, spiral coating, utilize the pattern coating of roller coating etc.
Embossing all sidedly also can middle vacant lot embossing.Also can utilize embossing to form information to wearer.According to the difference of the coating method of thermoplastic resin, embossed portion pattern visual different.By the coated pattern of identical embossing alteration of form thermoplastic resin, the shape of the application pattern of this thermoplastic resin is applied flexibly as pattern, make up with the pattern of embossing, by seeing the pattern that makes new advances like this.
If the coated pattern of full coat, owing to there is not the uncoated part of thermoplastic resin, therefore be applicable to any of the solid pattern of pushing pattern, fine rule.In addition also can the corresponding pattern that extends to the length direction of product.And, also can be by the labelling of ground wearing before and after using the pattern before and after obviously knowing such as arrow add to prevent to obscure, or character is heaved.
If the application pattern by slit type coater, then be fit to the pattern of the bigger area of a crimping.For example have solidly push pattern, though area is little but the pattern that pattern is tilting.The method that makes the side give prominence to, make user that the impression of anti-leak is arranged or make absorbent core partly seem to seem bigger etc. in addition in addition.In this coating method,, relaxed the hardness when fitting owing to there is blank parts.In addition, the pattern that extends to the product length direction is difficult to grasp the position relation with embossed portion because uncoated portion also extends to length direction, and is therefore not too suitable.
If utilize the coating of control joint,, therefore be fit to the pattern identical with the application pattern of utilizing slit type coater owing to form waveform.
If spiral coating, therefore the same whole coatings with full coat are fit to the pattern identical with the application pattern of full coat.Though uncoated portion is arranged, compare of light colorly with full coat, the advantage of not hardening is arranged.
If utilize the pattern coating of cylinder coating machine, because cylinder coating machine itself can transfer printing form the thermoplastic resin of pattern, therefore can try every possible means to make up the pattern that the pattern that material disconnects easily in embossing such as linear grade that extends to length direction or embossing form and design third dimension.
The method general using embossing processing of recess is set, preferred heat embossing processing.By each tone different liquid permeability sheet and dyed layer are implemented heat embossing processing simultaneously,, see owing near the color of easy identification dyed layer when therefore comparing at the recess that is processed to form by embossing with non-recess with the distance of dyed layer from liquid permeability sheet side.If dyed layer is through painted thermoplastic resin,, infiltrate liquid permeability sheet side, by pressure fixing, so preferred especially because the heat when utilizing embossing makes the thermoplastic resin fusion.If use through painted non-woven fabrics or thin film, different during with the use thermoplastic resin, be not to utilize heat to make the thermoplastic resin fusion, infiltrate liquid permeability sheet side and fix, but engage and have certain thickness liquid permeability sheet and dyed layer by implementing embossing simultaneously, make its distance approaching, therefore compare the easier tone of seeing the dyed layer of recess with non-recess.In addition, carry out the situation that embossing is processed to form pattern and compare with not painted, can relax the condition (temperature, pressure, gap) of embossing processing, the result can prevent that embossed portion and periphery thereof from becoming really up to the mark, therefore can reduce pain and the sense of discomfort that the friction in the use causes, the contact skin sense is good.
Embossing processing can use equipment commonly used to carry out.For example use the knurling rolls of the protuberance that is provided with required pattern to carry out embossing processing.By this embossing processing, can when forming pattern, engage a plurality of parts of constituting absorbent commodity and integrated.For example, engage liquid permeability sheet and absorber or engage liquid permeability sheet and opaque liquid sheet when also can on the liquid permeability sheet, recess be set by embossing processing.When dyed layer used and to contain the thermoplastic resin of coloring agent, preferred heat embossing processing was processed in embossing, can make liquid permeability sheet and absorber bonding via dyed layer by this heat embossing processing.In addition, if use the liquid permeability sheet that on whole liquid permeability sheet, applied the thermoplastic resin that contains coloring agent or lamination and contain the double-layer tablet of the thermoplastic resin of coloring agent, can make liquid permeability sheet and absorber bonding by heat embossing processing, and can make liquid permeability sheet and opaque liquid sheet bonding via dyed layer.
